Maximum likelihood phylogeny of Stylommatophora protein coding genes. Analysis in IQTREE yielded a single tree (log likelihood = -89104.188) under the mtZOA+F+I+G4 model. Branch support >50% is shown based on 10,000 ultra-fast bootstrap replicates. Helicoidea, Bradybaenidae, and Helicidae were recovered as monophyletic. Nodes A-E refer to rearrangements shown in Figure 4.
